Name: Mato Kuroi

Age: 12

Gender: Female

Appearance: Mato is a black-haired school girl with blue eyes. Over the past year, following the events of the Otherworld and Yomi, Mato has unintentionally let her appearance become more and more like her Other self Black Rock Shooter. Her hair has now grown past her waist and she wears them in two uneven twin tails since they were uneven to start out with when her hair was short. She has grown a little taller but she is still shorter than Yomi.

Other Self (if any): Black Rock Shooter

Fused?: No

Currently in the OtherWorld?: No

Personality: After Mato comes back from the Otherworld, she still stayed her outgoing and excitable personality as if nothing ever happened. But after her experience she has become more mature in a way.

History: In her first year of middle school, Mato comes upon Takanashi Yomi when looking for friends to make and decides to strike a conversation with her. Mato's bluntness and outward personality shocks Yomi initially, but the two become friends eventually. They begin to turn to each other for everything, and Mato eventually shows Yomi a special place where one can see a large view, and gives Yomi a cell phone charm with a star (identical to the one she has herself). Additionally, Mato's skill in basketball encourages Yomi to join the volleyball team.
Things change in her second year. The two are put in separate classes, and Mato finds and befriends the basketball team's manager Yuu from her class. Mato initially tries to get both Yuu and Yomi to be together with her at the same time, but ends up spending more time with Yuu. This makes Yomi feel "left out" and causes the rift to increase.
Mato starts to worry about Yomi, but things get serious when Yomi suddenly vanishes, not responding to any calls or texts. Initially Mato believes this means Yomi is avoiding her, but when two men come to her house asking about Yomi's disappearance, Mato breaks into tears and continues halfheartedly searching for Yomi.
Eventually, Mato gets a mysterious text from Yomi with nothing in it. Convinced that this is a clue, Mato runs out of her house (wearing a black jacket with a star on the back) and rides her bike up to the place she showed Yomi. She finds the phone charm she bought for Yomi and holds it to her chest, finally realizing what Yomi means to her.
A light erupts from the charm and envelops her, transporting her to a strange place filled with light. She meets Black★Rock Shooter there, and reconciles with her "other self", who offers to help Yomi. The two merge and both identify herself as Black★Rock Shooter, allowing both to save Yomi.
In the end, a reconciled Mato and Yomi walk home from school; however, Mato remains unaware that Yuu is in a dark state...
A year has now past and Mato is now a second year student.
